I can only speak for myself (and not other Jews) but as nice and harmless as this sounds, I do find it a bit creepy. Now, after all those centuries of (fill in the blank) to Jews, some Christians feel the need to return to the source--for what? Credibility? To prop up sagging interest? Because Jews got better music and dance? But the creepy part is that this attempted co-opting of Jewish cultural ways is being done by a religion that at its center denies the basic truth of Judaism--that G-d is G-d and humans are human. And that there can be no such thing (unless you're some sort of Roman or Egyptian pagan) as a man-God.
